Do you Viddy? Vine? Chat with friends in a Google Hangout? FaceTime with your sister (or your sister's Yorkie Terrier)?

From YouTube to Skype, video is taking over the universe, and unless you want to be caught on film with bedhead hair and dark circles, you have to be "camera ready" all the time.

"A bad angle can make your jaw look wider, create a double chin, or give viewers an up-the-nose shot," says Samantha Chapman, YouTube makeup artist sensation and one half of the Pixiwoo sisters. (Their channel has more than 145 million views.) Not only is Chapman an expert on angles and lighting, obviously she knows a thing or two about makeup for video. She always looks amazing -- even before she does a how-to. The good news? She's spilling her secrets.

So, whether you need to look good for a Skype interview or you just don't want to scare your sister's Yorkie, try these seven tricks.
